UNDER CLEARER ROLL.

Application filed December T 0 all 2071 cm may concern Be it known that I, NOAH E. LUoAs,a citizen of the United States, and a resident of Norwich, in the county of New London and State of Connecticut, have invented new and Improved Under Clearer Rolls, of which the following is a specification.

My invention relatesto the class of devices that are used in connection with the front, bottom drawing rolls in spinning frames, mules, etc., in the manufacture of various textiles, such as cotton, woolen, silk, etc, for catching and winding up broken threads lint and other waste for the purpose of keep ing said bottom drawing roll clean, and an object of my invention, among others, is to provide an under-clearer roll that will effectually catch and pick upbroken ends and thereby remove them from space surrounding the machine and consequently eliminate any danger of such ends catching upon other parts of the machine or upon material used in the spinning or other operations; and a furtl er object of my invention is to provide an under-clearer roll from which the material collected thereon may'be readily removed with little trouble and loss of time and without injury to said roll.

One form of under-clearer roll embodying my invention and in the construction and use of which the objects herein set out,

well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is a diagrammatic view illustrating a pair of drawing rolls and the operative relation of my improved HIlCl'6I-Cl62t1- or roll with respect thereto.

Figure 2 is a side View, scale enlarged, of my improved under-clearer roll with one end broken away to show its construction, and with a portion of the roll intermediate its ends broken out.

Figure 3 is a view in cross section through my improved roll, on a plane denoted by the dotted line 3-3 of Figure 2. V

Figure 4 is a side view of the roll.

Figure 5 is a detail view showing another form of journal.

In that application of my improved roll illustrated in Figure 1, but which is to be taken in no way in a restricted sense, said roll 5 is rotatably mounted in contact with the under side of a fluted drawing roll 6 of a well known arrangement of rolls employed in spinning and similar machines, this roll 12, 1923. Serial no. es0,0s1.

6 being mounted in cooperative relation with an upper roll 7, between which rolls 6 and yarn or strands 8 pass and by the operation of which rolls such yarn-or strands are drawn and evened.

My improvedunder-clearer roll 5 is constructed in a manner hereinafter described to promptly and effectually catch up the ends of all strands that may be broken and thus remove them from space surrounding the machine by causing them to adhere close: ly to the roll, such roll accumulating material, including such broken ends, in a manner to permit the accumulated mass to be readily removed from the roll. I

My improved under-clearer roll consists of a body 9, that is composed of any, suit able material, preferably cork, that'is compacted in any suitable manner and that has a groove 10 extending in a spiral direction along said body. This groove is filled with a material, preferably that may be packed into the groove and that will have the properties for catching loose threads, lint and the like. Felt has been found to satisfactorily answer this purpose, but it is contemplated that any other material having these characteristics may be employed. lhis filling 11, which I term a catcher, is preferably flush with the outside surface of the body 9. A plate 12 is secured to each end of the roll, each plate having a journal 13 projecting therefrom. A cap 14- preferably of non-metallic material, is secured to cover the plate 12, in the preferred form of construction the bearing 13 being threaded for threaded engagement with a hole in the cap. These parts may be secured in place on the end of the body in any desired manner, screws 15 effectively answering this purpose.

A roll constructed as above described will effect very satisfactory results, but for various reasons and under some conditions of use, I'have found that a metallic covering for the roll will produce advantageous results. To this end I envelop the body 9 with a sleeve 16, preferably of metal, this sleeve having a slot 17 registering with the groove 10 and through Which the filling material or catcher 11 may project, when such sleeve is used the filling preferably being flush with the outer surface of such sleeve.

As a further aid in catching up the threads and lint, I provide a spiral groove 18, shown herein as formed in the sleeve 16,

but when the sleeve 16 is omitted this groove may be formed in the outer surface ofthe body 9. This groove is formed with a shoulder 19 along one edge and it .tapers.

gradually from said shoulder to the-outer surface of the sleeve. I have found that this shoulder is a material aid in effecting the collection of loose threads, lint and the lilize.

lVhen the sleeve 16 is employed it is projected slightlybeyond thebody and its open end is threaded to receive the threaded edge of the plate 12, as shown in Figure 2 of the drawings.

lVhile I have shown and described herein my improved roll in one form as embodying an envelopingmetallic sleeve having a slot through which the catcher projects from the groove within the body ofthe roll, I contemplate as within the spirit and intent of of theinvention a structure in which said sleeve may be otherwise formed to receive or support the filling material or catcher, and it will, therefore, be understood, as contemplated within my invention, any roll having a spirally formed groove in its outer surface containing the filling material or catcher, whether such be formed in the outer surface of the roll, of whatsoever material, or Whether it be formed in a body so that the filling material will project through a slot in a sleeve enveloping said body.

In the construction shown in Figure 5 the journal is extended entirely through the roll, the plate 12 having a hole 20 through which the journal extends, the journal 13 in fact being integral with a rod 21, and the latter being secured at both ends in the same manner as shown at the one end in this figure.

In accordance with the provisions ofthe patent statutes I have describedtheprinciples of operation of my invention,together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that thedevice shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim- 1. An under-clearer roll having a groove extending in a spiral direction from end to end of the roll, said groove having a single shoulder located at one side thereof and facing in the direction of rotation of the roll, and ournals formed at the ends of said roll.

threads etc., located in said groove and com prising a comparatively smallportion of the outer surface of the roll and with the outer surfaceof the catcher being substantially flush with the outer surface of the roll.

4. An underrclearer roll comprising a body having a groove in its surface, an enveloping sleeve having a slot registering with said groove, and a catcher comprising material having an aflinity for lint, threads etc., located in said groove.

5. An under-clearer roll adapted to catch up lint, threads, etc., comprising a body, a sleeve enveloping said body aplatewith a journal extending therefrom secured to said body, and a cap. covering. said plate.

6. An under-clearer.roll adapted to catch up lint, threads, etc., comprising a body, a sleeve enveloping said body, a plate secured to said body and havinga journal extending therefrom, and a cap of non-metallic material secured to coversaid plate.

7. An under-clearer roll comprising a body having a spirally arrangedgroove, a metallic sleeve enveloping said body and having a slot registering with. saidgroove, a on tcher comprising material having .an affinity for threads, lint etc., located in said groove, a plate secured to said body and having a. journalprojecting therefrom, and a cap of non-metallic material secured .to cover said plate.

8. An .underclearer roll comprising a member having a slot in its wall, said slot being open atthe top and bottom and a catcher comprising material having an ailinity for lint, threads, etc., located within said member and projecting through said slot to the outer surface, of. said member, and means for supporting said member.

9. An underoleare-r roll having a smooth polished surface with a spiral groove therein, and a catcher comprising material having an affinity for lint,threads, etc., located in said groove withthe outer surface, of the catcher substantially flush with .the outer surface of said roll.
